Application filed December 13, 1899'. Serial No. 740,229- [No model.)

To all whom it may concern:

Be it known that I, T oMAs J. WHITNEY, a citizen of the UnitedStates,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new and use ful Improvement in Boiler-Feeders, whichimprovement is fully set forth in the following specification andaccompanying drawings.

My invention relatesto improvements in steam-boiler feeders; and itconsists of novel" means whereby water froma' street-main 'or' othersource of supply may be directed to the water-heater and from thence ina heated condition and by gravity to the steam-boi1er.

It also consists of means whereby the device may be operated'e'ither byhand or automatically, according-to requirements, provision being madebymea'ns of pipes and valves for regulating the circulation between themain boiler and the water-heater.

It further consists of novel details of construction, all as will behereinafter fully set forth, and particularly pointed out in the claims.

Similar numerals of reference indicate corresponding parts in thefigures.

Referring to the drawings, 1 designates a steam-boiler, above which isplaced a feedwater heater 2, the latter being provided with a pipe 3,which conducts the exhaust-steam from an engine into the upper portionof the outside casing of said heater, said exhauststeam serving to heatthe water within said heater before the same is fed to the boiler 1.

4L designates a pipe one end of which is connected with the upperportion of the inner casing of heater 2, its opposite end beingconnected with the chamber 5 in the casing 6, as best seen in Figs. 1,3. at, and 5.

7 designates a pipe one end of which is connected with the heater 2, itsopposite end being connected with the chamber 8 in the easing 6 and asbest seen in Figs. 1, 3, 6, and 7.

9 designates a pipe one end of which is connected with the upper portionof the boiler 1, its opposite end being connected with the chamber 10,as best seen in Figs. 1, 3, 4:, and 5.

11 designates a pipe one end of which is connected with the chamber 12,its opposite end being connected with the lower portion of the boiler 1.(See Figs. 1, 3, 6, and 7.)

13 designates a pipe which leads from the street-main or other source ofwater-supply and discharges into the chamber 14. (See Figs. 1, 3, 4, and5.)

The casing 6 is provided with a lid 15,which may be bolted or otherwisesecured thereto,

'as best seen in Fig. 4, it being noted that when said casing 6 and lid15 are placed together, as seen in Fig. 4, a chamber 16 will be formed.

17 designates a pipe one end of which is connected with the casing 6,its other end being connected with a shell or casing 18, within which isplaced a float 19, it being noted that said pipe 17 establishes acommunication between the interior of the shell or casing 18 steam fromthe cylinder 27 to any desired point.

38 designates a piston located within the cylinder 27 and adapted toreciprocate therein, it being noted that the rod 39 of said piston isconnected to the valve 40, as best seen in Fig. 11.

41 designates a counterbalance pivoted, as

at 42, to the extension of the cylinder-head and the chamber 16, as bestseen in Fig. 4. The shell or casing 18 has connected with its upperportion one end of a pipe 20, which leads from the steam-space in theboiler 1.

21 designates a pipe which leads from the boiler 1 to the lower portionof the shell or casing 18, so as to permit a portion of the water in theboiler 1 to pass through said pipe 21 and enter the shell 18 in order tooperate the float 19, located therewithin, for a purpose to behereinafter described. The float 19 has secured thereto a rod 22, whichfollows the rising and falling motions of the float 19,

due to the varying levels of water within the shell or casing 18. Theupper extremity of the rod 22 is connected with one end of a lever 23,which is pivoted, as at 24, to an extension 25 ot the head 26 of thesteam-cylinder 27, the latter being located within the space 16 formedby the casing 6 and lid 15, it being understood that said cylinder 27may be held firmly in position within the space 16 by any suitablemeans. The inner face of the lever 23 is provided with raised portions28 adjacent its pivotal point 24, as best seen in Figs. 13 and 18. Thespaces 29 between the raised portions or lugs 28 are adapted to receivethe projecting members 30 of the valve 31, (see Fig. 19,) so as to causesaid valve 31 when placed in position relative to the lever 23 to movein unison therewith.

The extension 25 in the head 26 of the cylinder 27 is provided withports 32, 33, and 34, which open into the space 16, (see Figs. 3, 4, 15,16, and 17,) and it is to be noted that the valve 31 is adapted to bemoved over said ports by the rocking motions of the lever 23, due to theraising and lowering of the float 19, occasioned by the varying levelsof the water in the shell 18. The port 32 leads into a passage 35,whichcommunicates with the upper portion of the interior of the cylinder 27,as best seen in Fig. 4. The port 33 leads into a passage 36, whichcommunicates with the lower portion of the interior of the cylinder 27,as seen in Fig. 4. The port 34 leads into a pipe 37, which directs theexhaustary, due to the friction of the valve 31 against the wall of theextension 25 of the cylinderhead 26, owing to steam-pressure againstsaid valve. When, however, the water-level has lowered sufficiently, theweight of the float 19 and also that portion of thelever 23 to the leftof its pivotal point 24 will exceed that of the weight 45, due to thedisplacement of water in the shell 18, and thus cause the float 19 torapidly drop, and consequently turn the lever 23, containing valve 31,on its pivot 24 and open the port 32, whereupon a communication will beestablished between the chamber 16 and the upper portion of the cylinder2.7, and steam from said chamber will enter the upper portion of thecylinder and force the piston 38 downwardly, thereby causing the valve40 to move from the position seen in Fig. 4 to that seen in Fig. 6.

When the water-level in the boiler 1 and shell 18 increases in height,the float 19 will not immediately rise with the Varying waterlevel, butwill remain stationary until the water-level reaches a point at whichits pressure upon the float 19 exceeds that of the friction of the valve31 against the extension 25 of the cylinder-head 26, whereupon saidfloat will rise rapidly, thereby opening the port 33 and closing theport 32 to the chamber 16, whereupon steam will pass from the chamber 16to the under side of the piston 38 and force the same upwardly, whilethe steam in the cylinder 27 and above the piston 38 will escape throughthe ports 32 and 34 and exhaust through the pipe 37. the under side ofthe piston 38 will cause the latter to rise, and thus move the valve 40from the position seen in Fig. 6 to that seen in Fig. 4.

46 designates a bell-crank lever journaled in the casing 6 and providedwith a handle 47, so that said lever 46 may be operated from the outsideof the casing 6 when desired.

The lever 46 has a projecting member 51, adapted to be brought incontact with the walls 52 and 53 of the lever 23 in order to rotate saidlever, and thus actuate the valve 31. (See Fig. 13.)

The steam-pressure on IIO The valve 40 has pivoted thereto one end of alink 54, (see Figs. 6 and 9,) the other end of said link being pivotedto the outer extremity of the arm of a lever 56, (see Figs. 9 and 20,)whose lower portion 57is journaled in a socket 53 in the casing 6, theportion 59 of said lever passing through a stuffing-box 60 in the lid15. The squared portion 61 of the lever 56 projects outside the lid 15,so as to receive a handle 62 (seen in dotted lines in Fig. 1) to permitsaid lever 56 to be operated from the exterior of the lid when desired,and for a purpose to he hereinafter described.

63 designates a pipe which leads into the chamber 16, said pipe beingsupplied with a suitable lubricant,which flows from the same and enterssaid chamber, where it commingles with the steam within said chamber,and thus causes the lubricant to reach all the portions of the devicewithin said chamber which require to be lubricated.

64 designates a vent-pipe connected with the upper portion of the innercasing of heater 2 to permit the air and impurities within said heaterto escape from the latter therethrough.

The operation is as follows: In order to primarily supply the boiler 1with water, the cock 65 (seen in Fig. 1)is closed and the cook 66opened, whereupon water from the streetmain or other source of supplywill flow through said cock 66 and enter the boiler 1, gradually iillingthe same, and when the desired water-level within the boiler has beenattained the cook 66 is closed and the cook 65 opened, whereupon thewater from the street-main or other source of supply will be directed bythe pipe 13 into the chamber 14. It is to be noted that the water-levelwithin the boiler 1 coincides with that within the shell or chamber 18and that the water-level Within said shell 18 is indicated by the gage67. Assuming that the water-level within the boiler l and interiorly ofthe shell 18 is at the height indicated at ct b in Figs. 1 and 4 andthat the piston 38 and valve 10 are in the positions seen in Figs. 4 and7, it will be.

apparent that the water directed to the chamber 14 by the feed-pipe 13will escape from said chamber 1& through the port 68 and enter thechamber 5 through the port 69 after passing through the passage 70 inthe valve 10 and will then [low from the chamber 5 through the pipe 4into the inner casing of heater 2 and from the latter through the pipe 7into the chamber 8, where it is confined by the valve 10 when in theposition seen in Figs. 1 and 7, and thus prevented from entering thechamber 12. During this time the ports 32 and 33 are closed by thevalve- 31 and no steam can enter the cylinder 27. The water within theboiler 1 will, owing to its being converted into steam and consumed,decrease in volume and its level will consequently become lower, as alsothat of the water within the shell 18, and the float 19 will,

as is evident, likewise lower and in so doing will cause the lever 23 toturn on its pivotal point, as at 24, and carry with it the valve 31, soas to cause the latter to occupy the position seen in Fig. 15, and thuspermit a portion of the steam within the space 16 to enter the port 32and passage 35 and be directed by the latter into the upper portion ofthe interior of the cylinder 27, the pressure of steam against thepiston 33 causing the same to lower and carry with it the valve 40,80that the latter will be brought into the position seen in Figs. 5 and 6,it being noted that the port 68 is now closed by said valve and thecommunication between the chambers let and 5 no longer exists.Consequently no water from the heater 2 can now enter the chamber 5; butsteam from the boiler 1 will be directed by the pipe 9 into the chamber10 and from the latter through the port 71 into the passage 70 of thevalve 40 and from said passage into the port 69 and then into thechamber 5 and from the latter through the pipe 4: into the upper portionof the inner casing of heater 2, so as to exert a pressure upon theWater within said heater, thus causing said water to flow bygravity fromthe same through the pipe 7 and into the chamber 8, from which itescapes through the port 72 and enters the passage 73 in the valve -10and from said passage through the port 74 into the chamber 12, as bestseen in Fig. 6, and from said chamber 12 through the pipe 11 and fromthe latter into the lower portion of the boiler 1. It is to be notedthat the steampressure within the heater 2 counterbalances the steampressure within the boiler 1 and that both pressures act in oppositedirections, whereby the water in the heater 2, being at a higher levelthan that in the boiler 1, must, as is evident, flow by gravity fromsaid heater into said boiler, and consequently the water will graduallyrise therein, as also in the shell 18, and cause the float 19 to riseand impart a partial rotation to the lever 23, thereby causing the valve31 to again close the port 32 and cut off the supply of steam to theupper portion of theinterior of the cylinder27. The Water within theshell 18 in rising will cause the float to likewise rise and at acertain time will cause the latter to carry the valve 31 into theposition seen in Fig. 16, it being noted that the port 33 is now incommunication with the space 16 and that a portion of the steam withinsaid space enters the port 33 and passage 36 and is directed by thelatter into the lower-portion of the interior of the cylinder 27, whilethe steam in the upper portion of the same is escaping from saidcylinder through the passage 35, port. 32, valve 31, port 34, andfinally through the pipe 37 to any desired point. The steam pressureagainst the under side of the piston 38 will cause the same to moveupwardly and return the valve 4Q to the position seen in Figs. 4 and 7,whereupon the heater 2 will again be supplied with water, ashereinbefore described.

Should the water from the street-main or other source of supply be shutoff for a considerable length of time, it will be evident that thewater'level within the boiler 1 and shell 18 against the water in theboiler 1 and both pressures being equal the water in the inner cut thatthe check-valve '75 will not, owing 70 to these conditions, obstruct theflowof waequal and the heat the same as in the steamboiler, theprecipitation of scaly matter takes 5 will gradually lower, owing to thefact that ter, since the pressure on both sides of said the water withinthe boiler 1 is being convalve are equal, it being understood that asverted into steam for driving an engine or the water in the inner casingof heater 2 is other purposes, and if such level should reach at ahigher level than the water in the boiler 75 a point below the pipe 21(seen in Figs. 1 and" 1 the weight of the water in the pipe 7 and [O 4)it will be apparent that the shell 18 will above the valve 75 willeasily open the same no longer contain water and that the float 19 whenpassing from the inner casing of heater therein will remain stationaryin the lower 2 into the water-feeder, from which latter it portion ofsaid shell 18, and thus produce no is directed by the pipe 11 into thelower por- 8o effect upon the valve 40. in order then to tion of theboiler 1.

I5 restore the water-level within the boiler 1 and In Figs. 21 and 22 Ihave shown a sectional shell 18 to its normal height when the supview ofthe preferred form of heater, it being ply from the street-main or othersource is noted that the inner shell 77 is inclined at an again turnedon, it may be necessary to operangle with respect to the head 78, withwhich 85 ate the valve 40 from the outside of the caslatter the pipes 4and 7 engage, said inner 2o ing 6, in which case the handle 62 (seen inshell 77 being secured to the flanged ring 79, Fig. 1) is manipulated soas to cause said which latter has secured thereto the outer valve 40 tooccupy either the position seen in flanged ring 80, to which is rivetedor other- Fig. 4 or else that seen in Fig. 5, and for the wise securedthe outer shell of the heater 2,- o purpose hereinbefore described. Ifdesired, it being of course understood that said head 25 the handle 47may be manipulated instead of 78 and the flanged rings 79 and 80 areprothe handle 62, in which case the valve 40 will vided with suitablegaskets and fastening debe operated by the action of the piston 38vices, as are familiar to those skilled in this and will be caused tooccupy either the posiart. 95 tion seen in Fig. 4 or else that seen inFig. 5, As has been already explained, the exhaust according torequirements, it being noted steam entering the pipe 3 can leave theheater that when the handle 47 is manipulated it through the pipe or anysuitable conduit, as will'operate the lever 23, and, as hereinbefore thepipe 81, provision being made, however, stated, the latter will causethe valve 31 to by the employment of the plate 82, having 100 slide overthe ports 32, 33, and 34 and 00- the perforations 83 therein, forfreeing the 35 cupy either the position seen in Fig. 15 or water ofcondensation from oil and other imelse that seen in Fig. 16, for thepurpose purities, which escape through the pipe 81 to hereinbeforedescribed. Should the pressure the desired point. of steam either aboveor below the piston 38 I also desire to call attention to the loca- 105prevent the handle 62 from being manipution and function of thecheck-valve 76, (seen 40 lated, this pressure may be removed by iminFigs. 1 and 23,) said check-valve being 10- parting a partial rotationto the handle 47, so cated inthe supply-feed-water pipe, preferas tocause the same to operate the lever 23, ably on the horizontal fbranchthereof and as which latter will then so locate the valve 31 near to theautomatic device as possible, so no that one or the other of the ports32 or 33 that the pressure from the heater will tend to will be made tocommunicate with the eX- close the valve proper, 84, as will beunderhaust-port 34, and thus permit the steam stood from Fig. 23, saidvalve being provided within the cylinder 27, which exerts its preswith aplurality of holes, which are in pracsure against the piston 38, toescape through tice about one-sixteenth of an inch in diame-' r15 siadexhaust-port, and the piston 38 no longer ter, wherefrom it will beapparent that the meeting with resistance of steam-pressure expansionofsteam against and in contact will not interfere with the manipulating ofwith the supply-water will not create a noise, said handle 62. The pipe7 is provided with but act as a muffler. 1 a check-valve 75, which isclosed by the pres- It is a well-known fact that lime, magne- 120 sureof waterfrom the boiler lwhena vacuum sium held in solution, and otherelements exists in the inner casing of heater 2, and contained inwaterif allowed to enterasteamthereby prevents water from said boilerfrom boiler under pressure with a high degree of flowing into the innercasing of heater 2, it heat are precipitated, and, coming in contactbeing apparent that such would be the case with the heated surfaces of asteam-boiler, r2 5 were it not for the check-valve 75. When a areconverted into what is generally known vacuum does not exist in theinner casing of as scale. The other impurities in water heater 2, thesteam-pressure against the waheld in suspension are, by a high degree ofter therein is equal to that against the Water heat, forced to thesurface of said water, and in the boiler 1, whereupon since the pressurethe air containedtherein is eliminated and I 30 on the water in theinner casing of heater 2 ascends to the top of the steam-boiler.

- is in an opposite direction to the pressure In my improved heater, thepressure being place in the heater, Where it remains in a granulatedform and is easily blown out with other sediments, as are also theimpurities held in suspension together With the accumulation of oxygenof the air in the heater. By thus supplying non-aerated water free fromimpurities held in solution and suspension the-liability of explosion isreduced to a minimum and the durability of a steam-boiler is greatlyincreased.

85 designates a pipe leading from the outer casing of the heater 2 forWithdrawing the oil obtained from the condensed steam and which floatsupon the Water in said outer casing, it being noted that said pipe 85 isprovided with a cook 86, which when opened permits the oil to escapefrom said outer casing, so as to be collected for future use, it beingevident that when the cook 86 is closed no oil can escape from the outercasing of the heater 2.
